Which detection and analysis technique captures a point-in-time picture of the entire stack during an incident?

Creating a snapshot using API calls is the most effective way to capture a point-in-time picture of the entire stack during an incident. Snapshots enable the preservation of the current state of a system, including all of its configurations, data, and processes. This technique is particularly useful in incident response, as it allows security teams to analyze the system as it was at the time of the incident, thereby providing critical context and insight into what may have occurred.

Using API calls to create these snapshots ensures that the collection is automated and can be accurately timestamped, making it easier to correlate other data collected during the incident. This approach is extremely valuable since it helps maintain the integrity of the data collected for future analysis, ensuring that no changes occur while the investigation is ongoing.

In contrast, the other techniques, while potentially useful for various purposes, do not capture the entirety of the system's state at a single point in time. For instance, collecting metadata during an alert may provide useful information related to specific activities, but it does not encompass the complete state of the system. Examining configuration data can help identify misconfigurations or vulnerabilities but lacks the context of runtime data. Reviewing data access logs is helpful for understanding how data was accessed and by whom, but it
